The deal calls for BAE's Integrated Flight Control System to be manufactured on Boeing's newest twin-isle aircraft.

The technology leads to better fuel efficiency and a safer ride.

"The key of our system is really to not be seen, and be behind the curtain, if you will, and just ensure the safe operation and the safe arrival. So that's what we would expect passengers to see-- that safe, reliable delivery of them to their destination," said Andy Corea, director of BAE Air Transport Programs.

The new technology reduces the amount of fuel needed to operate the aircraft by 12 percent.

Production on the Integrated Flight Control System began in June. The technology is expected to hit the skies on the Boeing 777X aircraft in 2019.
